Abstract: 591,847. Lay figures. SHAFARMAN, N. March 28, 1945, No. 7823. Convention date, June 8, 1944. [Class 52 (v)] A collapsable display form comprises a sheet of pliant material, e.g., cardboard, adapted to produce an adjustable bust effect in a garment. The sheet is doubled on itself to form a front and back member 10, 11 with low V-shaped openings 36 and connected together at their lower ends by one or two cords and buttons 14. The front member 10 is provided with slits 17, 21, 23a and struck up or partially severed portions 20, 23. The side portions 18 are bent under the lapel portions 19 to engage the portions 20 and the tabs 22 are tucked into the portions 23 or slits 23a to produce a bust effect. Slots 16 are provided as shown to allow vertical movement of the front on the back member in the deformation. The adjusting means comprises a cord 24 attached to a tab 25 at the upper end of the display form and adapted to pass through holes 27 on the front member 10 to form a loop 24a before being finally attached to a disc 29, slidably mounted on the cord 24. When the form is mounted on a stand the excess material of the garment may be gripped between the sides of the front and back members 10, 11 at their lower ends. The form is provided with weakening lines 35 and may or may not be tapered outwards as at 31. In modifications the back member 11 may be omitted entirely or it may be short if it is desired to suspend the form on a coat hanger.

Patent GB-1367900-A (GB)
Title: Apparatus for measuring two parameters of impedances
IPC: G01R27/02
Filed: 1971-06-30
Abstract: 1367900 Measuring impedances INSTITUT ELEKTRODINAMIKI AKADEMII NAUK UKRAINSKOI SSR 30 June 1971 8130/71 Heading G1U In apparatus for measuring the inductance and loss angle tangent of a coil 9, a balancing voltage U x  is applied to the coil 9, a reference voltage U o  is applied to a standard inductance 13, and a comparator 15 detects the difference I x  -I o  between the currents in the coil and inductance respectively and then reduces this difference to zero by adjusting two balance controls to vary the magnitude and phase of the balancing voltage, the balance controls being brought to their respective balance points independently of each other. The balancing voltage U x  is produced by adding together the voltage U<SP>0</SP> x  from an adjustably-tapped winding 4 and the voltage U y  provided at the output of a 90 degree phase shifter 5 which receives (7) an adjustable proportion of the voltage U<SP>0</SP> x . To reduce the out-of-balance current I x -I o  (phasor CD) to zero, a selectable first trial current, from a source 8, of either #I L  <O degrees or #I L  <180 degrees, is superimposed on the current I x . The phasor representing this trial current is inclined relative to U<SP>0</SP> x  at an angle equal to the phase angle of the unknown impedance. A control device 14 senses which of the two selectable phases of the trial current causes a decrease in the outof-balance current, and adjusts the tapping on winding 4 in the corresponding direction until the condition is reached where the addition of the trial current in either phase increases the out-ofbalance current. This will occur when the tip of the I x  phasor reaches d 1 , where Cd 1  is perpendicular to the phasor #I L , the locus of the I x  phasor as the tapping is adjusted being along OD since the magnitude of the balancing voltage U x  is changed but not its phase. When this minimum has been reached, the source 8 is rendered inoperative and a further such source 18 rendered operative to inject second selectable trial current #I tg # <O degrees or <180 degrees into the comparator 15 via a resistor 19, the phasor representing this trial current being parallel to U<SP>0</SP> x , and the control device 14 then adjusts the tapping on winding 7 in a similar manner. Since only the voltage U y  is being varied the locus of the tip of I x  phasor is now along a line perpendicular to I<SP>0</SP> x , and so I x  will be brought to coincide with the current I 0  through the standard inductance 13. Balance is thus achieved in only two steps because the locus of the I x  phasor when the second adjustment is being made is perpendicular to the trial current phasor during the first adjustment. Winding 7 may be the first one which is adjusted in which case the I x  phasor moves to C via the path D-d 2 -C.

IPC: B30B9/32
Filed: 1961-03-07
Abstract: 950,329. Consolidating scrap. DONKIN & CO. Ltd. Jan. 26, 1962 [March 7, 1961], No. 8238/61. Heading B3H. [Also in Division B5] A baling press of the kind comprising a press box having one side or lid pivotally arranged to be moved between an open and a closed position has its pivots mounted so as to be slidable substantially in the plane occupied by said slide when in its closed position. The press box 10 contains a ram 19 and has a lid 21 pivoted on a pin 15 and moved by means of an hydraulic unit 19a. The pin 15 is supported in a pair of blocks 16 which move longitudinally in a rectangular guide 17. When the lid is opened it is first withdrawn from the end of the box remote from the pivot until the clearance between the blocks and guides is taken up; similarly, when the lid is closed it is displaced longitudinally towards the box end remote from the pivot.  Since all corresponding edges of the lid and box are provided with cutting edges, the closing of the lid will tend to shear trapped scrap; any scrap trapped between said remote ends of the box and lid will not jam the lid shut due to the action of longitudinal withdrawal already mentioned. The side wall edges of the box may be upwardly inclined as described in Specification 950,328 and instead of longitudinal movement of the lid in the closed position, it may be moved transversely, i.e. axially of the pivot for clearing scrap jammed between the side walls and lid.

Title: Apparatus for Filling and Closing Envelope-Type Containers
IPC: B43M5/04
Filed: 1967-02-21
Abstract: 1,172,897. Filling and closing envelopes. McCALL PATTERN CO. 21 Feb., 1967 [2 March, 1966], No. 8281/67. Heading B8C. At a station A, Fig. 5, a compartment 95, of an intermittently rotating head 90, receives an envelope 36, and at a station B, the envelopes, which are held open, are filled with sheets. The head then carries the envelope to further stations C and D where its closure flap 38 is tucked in. The filled envelope is ejected at a station E. In the embodiment, whilst a compartment is rotated from A to B, the envelope, delivered between co-operating belts 74, 75 from a magazine (36), Fig. 1 (not shown), is held open by suction applied through blocks 97, 98, mounted on opposite walls of the compartment and by jaws (125), Fig. 8 (not shown), which press the envelope side edges together causing the mouth to bulge. At station B two sets of sheets 34, 35 are delivered between opposed belts 27, 44 and accelerating rollers 165, 166 into a shoot 190 for direction into the envelope, the shoot being rotatable to avoid contact with the upstanding flap of the following envelope. Whilst the compartment is moved between stations B and C, the upstanding flap 38 is folded by a plough 216. At station C members 230 and 235 rotate to tuck the flap into the envelope and at station D members 250 wipe the corners of the flap to avoid creases. Finally, at station E, the suction is cut off, the jaws (125) are opened, and the envelope is ejected between rollers 260 on to a discharge conveyer 263. If the sheets are not fully inserted into the envelope any upstanding portion will contact the flap folding plough 216 causing it to rotate partially about a shaft 220 to switch off the machine. The feed rollers 165, 165 may be adjustable to accommodate different sizes of sheet.
